Abstract

Low student interest remains a persistent issue in mathematics education. This study investigated the effectiveness of the Contextual Teaching and Learning (CTL) approach in enhancing students’ interest in learning mathematics. The research involved all students from a public junior high school in Yogyakarta, Indonesia. Using a quasi-experimental design, two eighth-grade classes were selected as the experimental and control groups, with 34 students in each class. Data were collected through a learning-interest questionnaire and classroom observations. The questionnaire employed a Likert scale and was administered before and after the treatment. Instrument validity was examined using the Pearson Product Moment correlation, while reliability was tested through Cronbach’s Alpha. The findings indicated that CTL significantly improved students’ learning interest compared with the conventional expository approach. Students in the experimental class showed greater enthusiasm, participation, and engagement during mathematics lessons because the learning activities were connected to real-life situations and meaningful experiences. Statistical analysis using a one-sample t-test and an independent-sample t-test at a 5% significance level confirmed that the increase in learning interest among students taught through CTL was significantly higher than that of students taught through expository instruction.

Abstract

Penelitian ini bertujuan untuk menganalisis perbedaan hasil pendidikan karakter antara mahasiswa berpesantren dan nonpesantren di Universitas Islam Multikultural (UIM) Yogya Yogyakarta sebagai lesson learned bagi Program Studi Pendidikan Matematika. Penelitian ini berfokus pada upaya memperoleh kejelasan mengenai perbedaan capaian pendidikan karakter serta mengevaluasi secara objektif keefektifan model pendidikan karakter yang diterapkan pada kedua kelompok mahasiswa. Nilai karakter yang dianalisis meliputi shidiq, istiqomah, fathonah, amanah, dan tabligh. Metode penelitian menggunakan pendekatan komparatif dengan pengumpulan data melalui angket, observasi, dan dokumentasi. Hasil penelitian menunjukkan adanya perbedaan capaian pendidikan karakter antara mahasiswa berpesantren dan nonpesantren, di mana mahasiswa berpesantren cenderung memiliki tingkat konsistensi dan internalisasi nilai karakter yang lebih tinggi. Berdasarkan pemeringkatan capaian, karakter istiqomah dan amanah menjadi nilai yang paling menonjol pada mahasiswa UIM Yogya Yogyakarta. Temuan ini memberikan implikasi penting bagi Program Studi Pendidikan Matematika dalam mengembangkan strategi pembelajaran yang lebih integratif dan berorientasi pada penguatan pendidikan karakter mahasiswa.
